Function macro_tools::orphan::derive::named_fields

pub fn named_fields<'a>(
    ast: &'a DeriveInput,
) -> Result<&'a Punctuated<Field, Comma>>

Extracts the named fields from a struct defined in a syn::DeriveInput.

This function specifically handles syn::DeriveInput that represent structs with named fields. It will return an error if the provided AST does not conform to these expectations.

Example

let ast = match syn::parse::< syn::DeriveInput >( input )
{
  Ok( syntax_tree ) => syntax_tree,
  Err( err ) => return Err( err ),
};
let fields = derive.named_fields( &ast );
